just wondering

I'm 22 and I've never had a UTI before . Is that normal ? The reason I ask is because I was dating this guy and he told me it was weird that I didnt have a taste or smell down there either. He said that it's a sign of an STD but I've been checked and I don't have any std's or anything (I've been checked a couple times since then ) . I don't know why I'm thinking about this I just thought it was weird .
